Following [1]}, the expected Rossiter-McLaughlin [2]}, [3]} amplitude is in the range \(K_{RM} \sim \)  1.5–3.0 m s\(^{-1}\) , since the \(v\sin i\)  of the star (< 2 km s\(^{-1}\) ) and the spin-orbit angle are not exactly defined. Collecting roughly ten data points within the transit (duration of \(1.8\pm 0.1\)  h) to achieve a precision better than the RM amplitude is well within reach for the current state-of-the-art spectrographs with sub-m s\(^{-1}\)  precision such as ESPRESSO [4]}, MAROON-X [5]}, or EXPRES [6]}.
